Receptor-mediated inhibition of serum-mediated proliferation. Concentration effect curves for the inhibition of proliferation were determined in HLF following exposure to a range of agonists targeting the (a) IP receptor, (b) EP receptor, (c) β2 adrenoceptor, (d) other GPCR and (e) non-receptors, in the presence of an EC80 concentration of serum for 24 h. For each individual experiment, data were normalised to the maximal proliferation observed with serum, and are expressed as means ± SEM for at least 3 independent experiments
